bánh đậu : (-but stats needs probably "quantian-'s cd http://dirk.eddelbuettel.com/quantian.html with "R-packages"!!!!) all "stats graphing" are expensive commercial products !!!! http://www.reunion.iufm.fr/Recherche/irem/Fiches/telecharger/Knomaths/knomath-1.1fr.iso this knomath contains at least the following : Geg http://www.infolaunch.com/~daveb/ geg is a program capable of drawing 2-dimensional mathematical functions within a nice user interface. e.g., f(x) = 3 + sin(x/2). geg allows you to view multiple functions simultaneously, with each function drawn in a different color. http://www.gnuplot.info/ Gnuplot supports various kinds of plots. In 2D, it can draw line, point, dot, box, histogram graphs or vector fields. In 3D, it supports line, point and dot surfaces, with or without hidden line removal. It supports color or grayscale surfaces and maps, even for non-equidistant and non-rectangular 3D data, otherwise it offers data gridding. Grace http://plasma-gate.weizmann.ac.il/Grace/ Grace is a WYSIWYG 2D plotting tool for the X Window System and M*tif. Graphthing http://graph.seul.org/ GraphThing is a tool that allows you to create, manipulate and study graphs. These "graphs" are mathematical objects (Graph Theory) that describe relationships between sets; they are not 2D plots, charts, or anything similar to that. http://scilabsoft.inria.fr/ Scilab is a scientific software package for numerical computations providing a powerful open computing environment for engineering and scientific applications. Developed since 1990 by researchers from INRIA and ENPC, it is now maintained and developed by Scilab Consortium since its creation in May 2003. hth ------------------------------------------------------------------------- Using Tomcat but need to do more?
